Abstract:

Ag∶InP nanocrystals with near|infrared(NIR) luminescence properties were synthesized and characterized by means of UV|Vis|NIR absorption spectroscopy, transmission electron microscopy(TEM) and X|ray powder diffraction(XRD). When Ag doping amount was 6% and doping temperature was 200 ℃, the Ag∶InP nanocrystals have the highest luminous efficiency. The emission of as|prepared samples was tunable in the near infrared region by tuning the size of samples. After the surface of Ag∶InP nanocrystals was coated with ZnSe, the stability of the particles was improved, and the fluorescence efficiency of the particles was increased from 20% to 45%. Also, the biomedical imaging results indicated that as|prepared Ag∶InP/ZnS nanocrystals could be a nice carrier with low toxicity.
